Abstract : An efficient sequential one-pot strategy for synthesizing polyfunctionalized quinazoline derivatives is presented. After selective amination of 4 at C-4 position, 2,6,8-trisubstituted 4-aminoquinazoline derivatives are prepared through one-pot chemoselective sequential tri-Suzuki-Miyaura or SNAr-bis-Suzuki-Miyaura reactions under microwave irradiation in an aqueous medium. This approach used with a variety of boronic acids affords the polysubstituted quinazoline derivatives in good to excellent yields in only a few steps and in environmentally benign solvent water.
